Title: Innovations by Chihiro Marumo
Introduction
Chihiro Marumo is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of measurement and control systems, holding a total of 3 patents. His work focuses on enhancing the precision and functionality of various instruments.
Latest Patents
One of Marumo's latest patents is a levelling method and apparatus. This innovative levelling apparatus utilizes a control system to obtain the average plane of an object placed on a mounting member. It does this by using the coordinates of at least three points in a specified area of the object, including points that are not on the same straight line. The system instructs the supporting mechanism to control the average plane to achieve the desired attitude, enabling three-dimensional attitude control of the object.
Another significant invention is a surface roughness measuring instrument. This instrument features a rotary drive mechanism that allows two rollers to support a sphere at three points. The driving torque applied to the sphere at these points ensures that all points achieve an equal tangential velocity. A detector arm is positioned between the mounting section and a tip section that holds skids in contact with the object being measured. This design allows for accurate and stable measurement of surface roughness in the circumferential direction of a body of rotation.
